The former Australian No. 1 is celebrating the release of his autobiography Game Changer, which covers his rise through the pro tennis circuit, as well as his role as one of Australia’s most prominent sports administrators.

Seven-time slam champion John McEnroe pays tribute to his fellow ‘Macca’ in the book’s foreword.

‘I remember watching Paul early on in my career in practice one day in the sweltering heat of Washington, DC, where he was working on going from a one to a two-handed backhand.

‘I had never seen it done that late in someone’s career, or have I ever since,’ he said.

McNamee, who is coaching Taiwanese pro Su-wei Hsieh, will be available to share stories and sign books from 6pm.
